Just to be perfectly clear on this:
To play any TuneIn station using just the remote (no app) you must assign each station to one of the WiiM presets first. The hardware remote will not allow you to search or browse TuneIn.
To play any TuneIn station in the context of clock alarms, you may pick any of your presets as the source for wake-up music. But you can also choose any station from TuneIn directly. No matter if you added them to your favourites.
Thank you very much! This is the most understandable answer for me. I just want the device to be in stores. I don't want it from Amazon, I like shopping with people

Amp Ultra has been played for over 8 hours in a room with a room temperature of 28Ā°C and 54% humidity. Volume 147% (85%,62%)
Current temperature.
temperature_cpu": "55", temperature_tmp102": "56"
Top panel: 42.7Ā°C
Bottom: 41.5Ā°C
Mine is very stable at medium volume
So what is considered too warm? There are times where the temperature on top of my Amp Ultra seems a little too excessive.
And by "a little too excessive" you mean what exactly ... ?
20Ā° C above ambient temperature surely is not excessive.
LIke, "wow that's really hot" and "my A/B amplifier doesn't get this hot" type of excessive heat.And by "a little too excessive" you mean what exactly ... ?
20Ā° C above ambient temperature surely is not excessive.
The WiiM Amp Ultra isn't always that hot but there are times I'm quite surprised. I have the Amp Ultra sitting on top of the cabinet with plenty of ventilation and no other heat source nearby. I'll measure it next time it gets that warm.
Side note: Does anyone know if there is a built-in fan within the WiiM Ultra that will eventually kick on?
My unit runs and plays music 24/7 and the top surface temp is often 110F (43C) and runs fine. Semiconductor junction temps can be very high, over 100C.

I have just measured mine, and the casing temperature is 36ā, and the internal temperatures are currently,
"temperature_cpu": "51", "temperature_tmp102": "50", in a room temperature of 21.5ā.
There is no built in fan, the casing is basically a large heatsink.

Semiconductors have a much longer lifetime at lower temperatures though. Something like a doubling of life for every 10C reduction in temperature.
Yes, speaking of the temperature range we're talking about here this is something like 150 years vs. 300 years.
It's not like we're going to use our kit in outer space.
The Amp Ultra is the hottest piece of gear Iāve had since the Tandberg TPA 3003.
I didn't know Class D would run hot, maybe it's not Class D?
I bought one and decided too much for my carry-on and returned it.
Still interested, even with the upcoming 3-Channel amp by that other company.
Now that I see 5.1 supported would be nice to have center channel volume in 2.1. I can do this with Kodi so seems possible?
I'd rather not add a center channel speaker in my small space.

Iāve been using class D since 2007. IcepowerASX2 (two each 125 and 250) first and since 2020 Hypex nCore (two each 252 and 100HF. The IcePower models ran cool, very low idle consumption. The nCore is different. In my setup (total 1200 W into 4 Ohm) they pull 50 W at idle and need proper cooling.
Don't worry, sure enough the WiiM Amp Ultra is Class D.
Class D amps are way more power efficient than Class A/B amps and switching mode power supplies are more efficient than linear ones. But nowadays we squeeze a preamp, a streamer, a DAC, a DSP and a 2 x 200 W power amp with a common PSU into one tiny box of 200 x 200 x 75 mm with no visible heatsink fans and finish it off with a 3.5" touchscreen.
When sitting idle (displaying the clock).for a couple of hours my WiiM Amp Ultr's case temperature is ~6ā° C above the ambient temperature. There's almost no difference to my WiiM Amp Pro.
The difference increases when the Amp Ultra is playing, but nothing I would worry about.

My Amp Ultra after a couple of hours of playback is just... warm? By no means hot, at least not Intel-based MacBook hot
= I would not worry much about it.My Amp Ultra after a couple of hours of playback is just... warm? By no means hot, at least not Intel-based MacBook hot
But this is why some of us are worried. There have been a couple times where my WiiM Amp Ultra is what I would consider extremely hot on the top. So the question becomes, if most people's Amp Ultra's are just warm...why is mine so hot? Is it a problem or is it just a difference in opinions of what constitutes as hot, warm, and cool? I have an Emotiva Bas X A3 A/B amplifier that stays much cooler on the top surface than does my Amp Ultra.

What is the temperature of your Amp Ultra casing? We need actual measurements.
What temperatures are shown using the following

Replace āip Address of your deviceā with the actual ip address.

Consensus seems to be that a twenty degree temperature rise is normal. If the ambient is 25 then 45 does feel quite hot. What temp does yours reach? Case temperature and CPU.

Absolutely true. I just wanted to share that mine is just fine and far from being "extremely hot" (regardless how defined). Readings are: 51C CPU, 46C tmp102.

That would probably give you a casing temperature of around 36 degrees C.
